Title:
IONIC LIQUID
Document Type and Number:
WIPO Patent Application WO/2006/070545
Kind Code:
A1
Abstract:
Disclosed is an ionic liquid having a low melting point, low viscosity and high conductivity. Specifically disclosed is an ionic liquid composed of at least one kind of anion represented by the following formula: [Z-BF3]- (wherein Z represents an alkyl group, an alkenyl group or a fluoroalkenyl group) and at least one kind of organic onium ion. Since this ionic liquid dissolves electrolytes such as lithium salts well, while having nonflammability and low viscosity, it can be suitably used as a solvent for electrolyte solutions in lithium batteries such as lithium secondary batteries or electric double layer capacitors. This ionic liquid is also suitable as a solvent or lubricant for electrochemical devices such as lithium secondary batteries, fuel cells, solar cells and electric double layer capacitors, or chemical reactions.
